It will befundelfstQOd that n'other similar steering knuckle will be vsrrlilajjly vpiwvte'ad tothe lOpposite end of the axle.

There' packing ring 32 which may will also be a of felt, interposed between the upower face of the end of the arm 15 said packing rin being preferably conned by an annular ange 15 formed on sald arm 15.

It is to be'understood that the above described connection between the cross rod l20 and the arm 15 will be employed at each en d of said rod -to connect it to the arm of the adjacent knuckle. It is quite .evident that the construction is not expensive, and that it may be easily assembled. To assemble the parts. the cap is of course removed, and then the stud 17 is passed upward through the two bushings 22, 23, into the hole '16 in thearm 15,' and then the nut 19 is screwed or securely fastened to said stud in said arm. After this tlhe cap' 30 is screwed on and the parts are in readiness to be supplied with oil and to `operate in the usual manner.

Fig. 3 shows in vertical section a different specific embodiment of the lubricating means herein claimed, or perhaps, more exactly,

substantially the same lubricating means, but in associationwitha different specific joint between the cross tie rod andy the steering arm of one of the knuckles; and Fig. 4 is a horizontal section in the plane of line 1--4 on Fig. 3.

. In the construction shown in Figs. 3 and 4: the arm, 15 isbent downward at its end 'a n'ut 27 that is screwed upon the upper bears upon the top 'forming thel vertical downwardly extended pivot stud 40. The cross tie rod 20 is provided at its end with an u wardly extended sleeve 25 which is' open at its upper end.

This stud 40 is rotatable within al split bushing 45 which is fitted within the-sleeve 25 restingupon an annular shoulder -26 therein against which the bushing isv held by end'of the sleeve 25, and down against two washers 28, 29. These embrace the `stud 40. vOne of4 the washers may be of metal and the. other one of felt. The lower@ felt washer of the split bushing and the top ofthe sleeve25and closely embraces the stud 40, thereby forming an-oil tight .'jointl The stud 40 is vformed with two'annular shoulders 41, 42, which-respectively engage the upper and lower ends of the-split ushing. The split bushing-has outwardly extended flanges 46, 47,- adjacent its ends. It is evident, therefore,

that there is formed,

bea packing washer 31 interposed -be-' rod. l r 4. The combination names around'and below said bushing a. chamber adapted to contain oil, and that this charnr is in open communication with the hollow interior ofthe cross tie "rod which ma therefore serve as 4an oil reservoir whic keeps this chamber supplied With the neces- Sary oil for lubricating the engaging surfaces of the stud and bushln Having described my lnvention, Iv claim:

1. In an automobile, the combination of a front axle, a steering knuckle pivoted to 'each 'end thereof on a vertical axis and l r0- videdwith asteering arm, a cross tie ro for 4connecting said steering arms,-which cross tie rod has adjacent each end a vertical'sleve which is closed at its lower end, abearng and `each sleeve being provided with an annular shoulder which rests upon saidtlange.

2. In an automobile, the combination of a front axle, a steering knuckle pivoted to each end thereof on a vertical axis and provided with a steering arm, a hollow cross tie rod for connecting said steering arms,-which cross tie rod has adjacent each-end a vertical sleeve which is closed at its lower end and which communicates with the hollow interior of the cross tie rod, a bearing stud which is rigid with and projects from each steering arm downward into the bearing sleeve in the adjacent end of the cross tie rod and is rotatively mounted therein, and means to hold the Studs in said bearing sleeves.

' 3. In an automobile, Ythe lcombination-of the two steeringiknuokles each having an arm, a -pivot stud fixed to and projecting down from each of said arms, a tubular cross rod having verticall` .disposed bearing sleeves at its en s 'which s eeves embrace and "MJ stud .which is rigid with and projects from serve as bearings for said studs, an annular bearing sleeve to the interior of said cross with an varm iixed to the steering knuckle 'of an automobile, of a stud removably fixed to said 'arm and extending downward therefrom and havin -an annular flange ,at itslower end, a vtugular cross rod, two wertical bushings fixed inthe end'of said crse rod and rotatably mounted upon said stud with the lower end of the lower .bushing resting upon the flange on said stud, and a cap removablyfixed to the cross rod and covering andinclosing the @musa f y lfgojecting lover end ofvsaid sudnnd signature in the prsonw rof two wit'.hneslssf.`
